The heal skill states:
Treating deadly wounds heals 1 point of damage per level of creature being treated. If you exceed the DC by 5 add your WIS modifier (if positive) to that amount.
Adding my WIS mod to "that amount" is vague in my opinion. The only "that amount" previously discussed is 1 point per level of creature. If that's the case then when I treat someone of level 3 and I have a WIS mod of 4 then a heal check will heal for 15 pts of damage. (1 + WIS = 5 × 3 levels of creature = 15) I assume that isn't the case and instead it's adding WIS mod to total making it 7 pts. (1 × level = 3 + WIS = 7)
Can someone provide an example of how treat deadly wounds should work and clarification of the rule?
